Let Nyan Cat show you your buffer position in mode line. Parts of the code and overall inspiration come from SmlModeLine.
To get NyanMode, go to mode page or GitHub repository.

If you use a custom ‘mode-line-format’, ‘M-x nyan-mode’ may not work for you. Instead, you can put (:eval (list (nyan-create))) somewhere in your ‘mode-line-format’.
If you want to use a color other than “space blue”, change #003366 in img/*.xpm into another color, or None for transparent. Example:
ModeLineConfiguration CategoryModeLine? CategoryModeLineConfiguration?
